The song, which was launched on Wednesday, was trending in 62 countries across the world at the same time. The official video got 1.6 million views on Facebook and 1.6 million on YouTube since its release, said a statement.
"Gerua" brings back some romantic moments of the "Dilwale Dulhania Le Jayenge" couple back on the big screen. The music is given by Pritam Chakraborty and is sung by Arijit Singh and Antara Mitra.
And Pritam is elated by the response.
"The reaction on 'Gerua' from everywhere has been very heart-warming," Pritam said.
With hues of bright colours like orange, the romantic number paints a dreamy image with Shah Rukh and Kajol declaring love for each other.
Mostly shot in Iceland, the song's visuals are a delight to watch with glimpses of lush green mountains tops, waterfalls, rainbow or a wrecked plane on a deserted spot.
The Rohit Shetty directorial also stars Varun Dhawan, Kriti Sanon, Johnny Lever, Boman Irani and Sanjay Mishra.
The family entertainer with a perfect blend of action, romance and comedy is produced by Red Chillies Entertainments in association with Rohit Shetty Productions and will release on December 18.
